Costa Rica were thought of as the least intimidating team in the Group of Death that is World Cup group D with Italy, Uruguay and England. Dangerous if underestimated, but not at the level of the three past winners in their midst, despite Uruguay's struggles in qualifying. And Uruguay found out the "dangerous if underestimated" part the hard way in their first match, losing 3-1 in remarkable fashion.

With Luis Suarez on the bench, Uruguay took a 1-0 lead in the first half from a 24th-minute Edinson Cavani penalty after teammate Diego Lugano was hauled down in the box with an American football tackle. With that lead, Uruguay seemed to get a little bit too comfortable and Costa Rica took advantage in stunning fashion.

Arsenal striker Joel Campbell struck first for Los Ticos in the 54th minute with a shot that completely froze goalkeeper Fernando Muslera.

Then, before Uruguay could even process what had happened, Costa Rica scored again with a low header from Oscar Duarte just three minutes later.

Finally, Costa Rica struck one more unexpected blow with a goal in the 84th minute from substitute Marco Urena, who entered the match just a minute earlier. And to ensure the match couldn't have gone any worse for the 2011 Copa America winners, defender Maxi Pereira was shown a straight red (the first of the tournament) deep into injury time for a sweeping kick at Campbell's legs.

This marked the first time Costa Rica have scored three goals in a World Cup match and the first time since 2002 that they've won a game in the tournament.

Man of the Match

Joel Campbell, Costa Rica — He scored that first goal for his side and reminded England and Italy why they should be wary of him going forward. He's prove to be a danger man in the Champions League and now he's continuing that here.

In a group where every point is vital, this does severe damage to Uruguay's hopes of advancing and gives Costa Rica a suddenly not unthinkable shot at mounting a challenge for a top two finish of their own. This World Cup is madness.
